Embodiment Construction

[0041]The present application provides a wheeled carrying apparatus that includes a standing frame, and a plurality of wheel assemblies provided at a bottom of the standing frame. The wheel assemblies can be controllably locked and unlocked in horizontal orientation with respect to a standing frame, wherein an unlocked wheel assembly can rotate relative to the standing frame for changing the horizontal orientation of a wheel axis. According to the needs, some of the wheel assemblies are locked while others are unlocked, or all of the wheel assemblies can be unlocked at the same time as desired. Accordingly, the wheeled carrying apparatuses can be more flexible in use and have better maneuverability. Embodiments of the wheeled carrying apparatus described herein include child stroller apparatuses. However, it will be appreciated that wheeled carrying apparatuses that may incorporate the structures and features described herein can include, without limitation, child stroller apparatus...

Abstract

A wheeled carrying apparatus includes a handle frame rotatable relative to a standing frame between a first and a second position, a wheel mount pivotally connected with the standing frame, a wheel mount latch adapted to engage and lock the wheel mount with respect to the standing frame and to disengage and unlock the wheel mount so that it is rotatable for changing orientation of a wheel axis, a link actuator coupled to the wheel mount latch via a linking part that is movable as the handle frame rotates for causing the wheel mount latch to engage or disengage the wheel mount, and a release mechanism including a cable assembly that couples an operating part carried with the handle frame to the wheel mount latch, the operating part being operable to cause the wheel mount latch to disengage the wheel mount in the first position of the handle frame.

Description

CROSS-REFERENCE TO RELATED APPLICATION(S)[0001]This application respectively claims priority to China patent application no. 201910858955.3 filed on Sep. 11, 2019, and to China patent application no. 202010370191.6 filed on Apr. 30, 2020.BACKGROUND1. Field of the Invention[0002]The present invention relates to wheeled carrying apparatuses.2. Description of the Related Art[0003]Caregivers usually rely on a stroller apparatus to transport babies and children. Most stroller apparatuses typically have front wheels that can freely rotate horizontally relative to the stroller frame for changing the orientation of the wheel axes, and rear wheels that cannot rotate horizontally and have a fixed wheel axis oriented transversally. As a result, it may not be easy for the stroller apparatus to turn around in an environment of limited space.[0004]Therefore, there is a need for an improved design that can offer better maneuverability and address at least the foregoing issues.SUMMARY[0005]The pres...
